UCC24612: Technical Inquiries

Part Number: UCC24612

Hi Experts,

Good day.

I have a question about chip: UCC24612.

I want to use this with a DC voltage of 400 Can we use a resistor divider?

I want to use it in the LLC converter, but the secondary voltage is 400V so if we use an SR driver. so if we use an SR driver. 

It seems the voltage is out of the range, so we want to know if we use a resistor divider to half the dc voltage, can the SR driver still work correctly?

My worry is that since the chip is negative voltage sensing, so if we use a resistor divider, I'm afraid that the sensing will not work. The mosfet we choose has a 0.95 VSD.

Another question is that, if I want to use it in a full bridge circuit, should I add an additional bootstrap circuit? Or just use the chip as a signal generator, and use another half-bridge driver to drive the bridge arm?

Please advise.


Regards,

Josel
